德胜煤矿基建期间的通风系统优化设计研究

Study on the optimization design of ventilation system during the construction of Desheng coal mine

山西德胜煤矿基建的一期工期完成后,二、三期工程井巷开拓布置会导致通风系统的需求发生变化,根据二、三期工程井巷开拓布置工况,分三个阶段对通风系统进行优化改造,并对地面临时主要通风机选型计算,有效保障了井下通风系统的安全可靠稳定运行。

After the completion of the first phase of the infrastructure construction period of Desheng coal mine in Shanxi Province,the development and layout of the shafts and lanes in the second and third phase of the project will lead to the change of the demand of the ventilation system.According to the conditions of the development and layout of the shafts and lanes in the second and third phase of the project,the ventilation system is optimized in three stages,and the selection and calculation of the temporary main fans on the ground effectively ensure the safe,reliable and stable operation of the underground ventilation system.
